When to use drag & drop

A study to determine when to use drag and drop ...

"One of the great challenges of Interaction Design these days is that we now have a plethora of new ways to design interaction on the web than we did just a few short years ago. Drag and drop is probably one of the best - creating a sense of empowerment over the interface that can sometimes result in an almost joyful user experience.

Despite the fact that we’ve been designing with drag and drop for a while now, it’s taken this long for me to have the opportunity to do some good solid user testing with users comparing drag and drop with more traditional interaction styles. That is … clicking

In the test that were we performing we were (amongst other things) examining the use of drag and drop and clicking to perform two types of tasks: to select objects and place them onto a stage, and to manipulate objects on a stage.

One interface used drag and drop for both tasks. One interface used click to select and drag and drop to manipulate.

When users were interacting with the prototype that used drag and drop for both functions it was common for them to make unsolicited comments about the interface - generally expressions of delight at the responsiveness of the interface and the novelty of the interaction method. Of course, drag and drop is not really so novel - many users are accustomed to this method, and we found that no users (of the 15 we tested) were unfamiliar with the drag and drop method or had any difficulties understanding how they were expected to achieve their task using drag and drop. (The interface did include a small instruction to drag and drop onto the stage)."   (Continued via Disambiguity)   [Usability Resources]
